The court noted that approval given by Singh, who was also the Minister of Coal at that time, was in "violation" of the established procedure.

It also said that Singh had kept the coal portfolio with him and thus "prima facie he cannot claim that being Prime Minister he could not be expected to personally look into the minute details of each and every case."

"His (Singh's) approval in violation of the established procedure and already approved guidelines clearly resulted in defeating the efforts of NLC to establish a 2000 MW Power Plant in Odisha. His action thus prima facie resulted in loss to NLC which was a PSU and facilitated windfall profits to a private company i.e. M/s HINDALCO," the judge said.

The court also observed that "compromising" the status of Talabira-III coal block, which was reserved for PSU and was with Coal India's arm, Mahanadi Coalfields Ltd (MCL), and allocating excess coal to HINDALCO again "prima facie crops up as an incriminating circumstance against him (Singh)."

Detailing the role of Singh, the court said he had allowed the matter pertaining to allocation of Talabira-II coal block to be "reopened" even though he himself had permitted approval of minutes of 25th Screening Committee recommending allocation of allocating the said block to NLC.

"The repeated reminders from PMO, written as well as telephonic, to MOC (Ministry of Coal) to expeditiously process the matter in view of the letters received from Kumar Mangalam Birla also prima facie indicate the extra undue interest shown by the PMO in the matter," it said.

While holding that Singh cannot take the defence that being Prime Minister he could not be expected to personally look into the minute details of each and every case, the judge said, "I may, however, state that the present case stands on a different footing as here Dr Manmohan Singh did not act in the capacity of a Prime Minister but as a Minster of Coal."
